Abstract

resumo patente de invenção: "disposição de mola pneumática com válvula de controle integrada" a presente invenção refere-se a uma disposição de mola pneumática com pelo menos uma válvula de controle integrada (1) para a aplicação de um ar comprimido entre um tubo externo (2), um tubo de rolamento (3) e uma câmara de pressão (5) que interliga estes e que é formada por um fole de mola pneumática (4), sendo que a pelo menos uma válvula de controle integrada (1) pode ser comandada com várias posições de comutação, para o ajuste de nível através de meios de acionamento mecânicos integrados, em função de um curso de levantamento da mola pneumática, sendo que, além disso, a câmara de pressão (5) abrange uma mola de pressão (8) localizada frontalmente entre uma parte superior de tubo (6) e uma parte inferior de tubo (7) do tubo externo (2), e uma alavanca (9) ligada mecanicamente com a pelo menos uma válvula de controle integrada (1) pode ser acionada através de pelo menos um nariz de acionamento (10) disposto em uma face frontal da parte inferior de tubo (7), para concretizar uma característica escalonada de uma aeração e exaustão da câmara de pressão (5).Summary of the invention: "Air spring arrangement with integrated control valve" The present invention relates to a pneumatic spring arrangement with at least one integrated control valve (1) for the application of compressed air between an outer tube. (2), a bearing tube (3) and a pressure chamber (5) interconnecting them and formed by a pneumatic spring bellows (4), with at least one integrated control valve (1) being able to It can be controlled with various switching positions for level adjustment by means of integrated mechanical drive means according to a lifting stroke of the air spring, and in addition the pressure chamber (5) comprises a pressure spring (8) Frontally located between a pipe top (6) and a pipe bottom (7) of the outer pipe (2), and a lever (9) mechanically connected with at least one integrated control valve (1) can be triggered through s of at least one drive nose (10) disposed on a front face of the underside of pipe (7), to realize a staggered feature of a pressure chamber aeration and exhaust (5).
